Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of oxygen inhalation devices, in particular to a pressure-bearing and sealed sound transmitting device for an oxygen cabin. Background Art
[0002] As we all know, an oxygen recompression chamber places a patient inside a chamber where oxygen is used to create a treatment environment with a pressure higher than one atmosphere. The patient receives treatment directly by breathing oxygen from the chamber's atmosphere at this pressure. Patients undergoing treatment in the chamber require constant communication with the outside world to understand the treatment status and provide guidance on proper operation and handling. To achieve this, existing oxygen recompression chambers utilize an intercom system. However, since intercom systems are electrical, using them in an oxygen environment presents certain safety risks.
[0003] Currently available oxygen recompression chambers are subject to national standards requiring that the total power of electrical equipment entering the chamber not exceed 5W. However, existing speakers on the market generally exceed 5W, making them unsuitable for installation inside these chambers. Oxygen chambers are pressurized, sealed steel structures. External speakers typically cannot transmit or communicate with each other. These speakers are crucial for communication between staff outside the chamber and patients inside. If the transmitted voice is unclear, communication becomes difficult, leading to miscommunication between doctors and patients and potentially medical accidents. Therefore, during the product development and design process, a device that can withstand pressure, provide a seal, and transmit sound is required. The existing installation method, which involves directly fixing the speaker to the exterior of the chamber, has been found to have drawbacks: the transmitted sound is extremely weak, preventing staff outside the chamber from communicating properly with patients inside, potentially posing a risk of medical accidents.
